NAME
     df - summarize free disk space

SYNOPSIS
     df [-aikP]  [-t  fstype]  [+all]  [+inodes]  [+type  fstype]
     [+kilobytes] [+portability] [path...]

DESCRIPTION
     This manual page  documents  the  GNU  version  of  df.   df
     displays  the amount of disk space available on the filesys-
     tem containing each argument pathname.  If no pathnames  are
     given, the space available on all currently mounted filesys-
     tems is shown.  Disk space is shown in 1K blocks by default,
     unless  the  environment variable POSIX_ME_HARDER is set, in
     which case 512-byte blocks are used.

     If an argument is the full pathname of a  disk  device  node
     containing  a  mounted filesystem, df shows the space avail-
     able on that filesystem rather than on the  filesystem  con-
     taining  the  device  node  (which is almost always the root
     filesystem).  This version of df  can  not  show  the  space
     available on unmounted filesystems, because on most kinds of
     systems  doing  so  requires   very   nonportable   intimate
     knowledge of filesystem structures.

  OPTIONS
     -_a, +_a_l_l
          Include in the listing filesystems that have 0  blocks,
          which  are  omitted  by  default.  Such filesystems are
          typically special-purpose pseudo-filesystems,  such  as
          automounter entries.

     -_i, +_i_n_o_d_e_s
          List inode usage information instead  of  block  usage.
          An  inode is a special kind of disk block that contains
          information about a file, such as  its  owner,  permis-
          sions, timestamps, and location on the disk.

     -_k, +_k_i_l_o_b_y_t_e_s
          Print sizes in 1K blocks instead  of  512-byte  blocks.
          This     overrides     the     environment     variable
          POSIX_ME_HARDER.

     -_P, +_p_o_r_t_a_b_i_l_i_t_y
          Use the POSIX output format.  This is like the  default
          format  except that the information about each filesys-
          tem is always printed on exactly one line; a mount dev-
          ice  is never put on a line by itself.  This means that
          if the mount device name is  more  than  20  characters
          long  (as  for  some  network  mounts), the columns are
          misaligned.

     -_t, +_t_y_p_e _f_s_t_y_p_e
          Limit the listing to filesystems of type _f_s_t_y_p_e.   Mul-
          tiple  filesystem types can be shown by giving multiple
          -_t options.   By  default,  all  filesystem  types  are
          listed.
